A broadside array operating at 100 cm wavelength consist of 4 half-wave dipoles spaced 50 cm apart. Each element carries radio frequency current in the same phase and of magnitude 0.5 A. The radiated power will be

196 W

73 W

36.5 W

18.25 W

Correct Answer: 196 W

Explanation:

P = n . I² . R_r, where R_r = 80p² Ω.

n = 4.
